This course spans approximately 60 hours over one semester and provides 6 credits. AIMS AND CONTENT LEARNING OUTCOMES The main objective of this course is to introduce 2nd year students to the concepts of Fluid Mechanics, such as fluid and flow properties, fluid behavior at rest and in motion. Fundamental equations, like mass and momentum balances for simple one-dimensional steady flows, will be formally derived and applied to the study of pipe. LEARNING OUTCOMES (FURTHER INFO) Evaluation of static forces on immersed plane and curved surfaces. Design and analysis of simple pipe networks, fluid machineries. TEACHING METHODS The lectures are organized in about 12 lessons. Eachone characterised by a first theoretical part and a second part of practice, with example problems. SYLLABUS/CONTENT Fundamentals - Fluid properties and classification. Cinematics of fluids. Eulerian and Lagrangian description of motion. Cauchy's continuum, forces, pressure and stresses. Stress in a fluid at rest. Hydrostatic law. Stress in a fluid in motion. Material and local derivatives. Conservation of mass and momentum principle in integral and local form. Inviscid fluid and the Bernoulli's law. Fluid at rest: hydrostatics - Pressure distribution in an uncompressible fluid and in a compressible, barotropic fluid. Forces on immersed plane and curved surfaces. Buoyancy. Stability of floating and immersed bodies. Fluid in motion: one-dimensional flow - Definition of cross-averaged quantities. Conservation of mass and momentum principle for a one dimensional flow: continuity and momentum equations. Flow in pipes - Uniform and steady flow in a pipe. Friction losses. Local dissipations of energy. Design and analysis of simple pipe networks, fluid machineries.

There will be two midterm exams that will grant, if passed, direct admission to the final oral examination. ASSESSMENT METHODS Written exam consists in 4 exercises on the following items: 1) Forces on immersed plane surface. 2) Forces on immersed curved surface. 3) Conservation of mass and momentum principles in integral form 4) Design and analysis of simple pipe networks. The oral exam consists of a discussion of the written exam, plus two or three questions on the topics explained during the lessons.
